The Crimean Khanate deserves a spot on the roster? A country whose role in history was literally to just be the minor leagues for prospective Ottoman ########### and a glorified slave bazaar for everybody else in Eastern Europe. That civilization?
We already have the Tatars in general as a campaign-only civ, and their flag uses similar colors and iconography to the Crimean Tatar flag used today.
There’s a better chance, I kid you not, of an umbrella Australian aboriginal civilization making it into this game than there is of us getting a Crimean civ in any capacity.
